Local polarization dynamics in chemical solution deposited PZT capacitors by switching spectroscopy PFM

摘要

The local polarization dynamics in chemical solution deposited PZT thin film capacitors were studied using spatially resolved spectroscopic measurements. 2D maps of switchable polarization as a function of bias window allow the voltage-dependence and spatial distribution of regions with reversible and irreversible wall motion to be mapped. Extension of the measurements to mapping the disorder potential controlling domain wall pinning enabling development of a spatially resolved Preisach model is discussed.
